Our high pressure, non-conductive NC-SERIES hoses and couplers are rated at 10,000 psi working pressure. The hose ends are covered with a thick clear jacket of heavy duty shrink wrap to reduce the risk of hose bursts at these points. As a result of injuries sustained by operators via broken or damaged high pressure hoses Huskie has developed a replacement hose improvement program for our customers. Consult your representative for information. Our hoses come standard with 3/8 in. male/female couplers.
